HEATING ATTACHIVIENT FOR GRATES AND FIREPLACES.

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed June 25,1907. Serial No. 380.786.

To all whom it may concern:

Be it known that I, FRANK A. DELPH, a citizen of the United States, and aresident of New Orleans, in the Parish of Orleans and State of Louisiana, have invented an Improved Heating Attachment for Grates and Fireplaces, of which the following is a specification.

My invention is an improvement upon that for which I filed an application for Patent No. 342,988, on November 12, 1906.

In my former invention I have attached U-shape return flues or pipes to a plate adapted to cover the upper portion of afireplace or grate front, the same being hinged at one side so as to swing laterally and thus open the space above the grate or fire-hearth whenever required. When thesaid plate is closed and a baffle plate is arranged in the fire space behind it, the products of combustion are directed through the flues or pipes and thus the latter become effective for heating an apartment with a comparatively small consumption of fuel.

My present invention. is embodied in an attachment for the fireplace, or grate, frame, the same consisting of a supplemental frame, to which the plate having the heating flues or pi es attached is hinged so as to swing lateral 'y thereon.

The inventionfurther includes an im roved means for securing such supplementa frame to the main frame, and anchoring both The baffle plate is normally supported upon such anchoring devices and is connected with the hinged grate front so as to be drawn upward to a vertical position when the grate front is swung laterally.

The details of construction, arrangement, and operation of parts are as hereinafter described and illustrated in the accompanying drawing, in wh ich Figure 1 is a front view of a grate or fire place front showing my improved attachment. Fig. 2 is a vertical transverse section ontheline22 of Fig. 1. Fig. 3 is aperspective view of the supplemental frame and anchoring device attached thereto. Fig. 4 is a horizontal section taken above the baffle plate when lying in working position.

A indicates a grate, and B a frame such as ordinarily employed in connection therewith. 0 indicates the plate which is adapted to close the space above the grate A, and to form to the shape or contour of the inner portion of such frame B. In this instance, therefore, it is semicircular as shown. Such frame is provided on the front with a rib and with an exterior flange e that extends over the edge of the frame B. For securing it to such frame and for anchoring both frames B and E, I provide the attachment F applied to frame E, see Figs. 2 and 3, the same consisting of a metal bar having a front flange or lug f which is provided with holes for reception of bolts or rivets that secure it to a lug 6 formed on and projecting laterally from the inner flange e of the supplemental frame E. Directly in rear of such flange, the bar F is provided with another, f which projects from 'the back of the same and is in contact with the rear side of the grate frame B see especially Fig. 4. Thus, when the bar F is securely attached to the lug 6 the rear lug f is drawn tightly against the fireplace frame B and held securely in place. The inner flanged end f 2 of bar F is in practice anchored in the wall of the fireplace. Two holes are provided in the bar F, near its inner end to receive nails or spikes for holding the bar to the brick nook. The ends of the supplemental frame are provided with toes or feet a which as shown in Fig. 1, rest upon the top bar on the grate A.

The swinging plate O is hinged to lugs 6 cast integrally with the frame E.

In 1 the plate C with its attached flues or pipes D is shown swung off laterally; but in Figs. 2 and 4 it is shown in a closed position, in which case it fits within the rib 6 formed on the front of the supplemental frame E. For fastening it in this position, I employ a device consisting of a rotary handle G, having on its inner end a prong or finger g, which, when the handle is turned to the vertical position, engages the inner side of the grate frame B as shown in Fig. 2.

In addition to anchoring the frames B, E,

and securing them together as before stated, the bars F, which, as shown in Fig. 4, are directly opposite each other on the sides of the fireplace or grate opening, serve as rests and supports for the division, or baffle, plate Hi In Figs. 2 and 4 such plate is shown in its normal position or resting upon the bars F whereby it serves to interrupt the direct upward course of the flame or products of combustion from the fuel burning in the grate, so that they are c'ompelled to pass through the return flues D as indicated by arrows Fig. 2. It is obviously necessary, however, that such plate shall be raised, and thus allow free upward passage of flame and gaseous products of combustion Whenever the grate or fireplace front 0 with its attached fines is swung off laterally as in Fig. 1. I have, therefore, provided means whereby such baffle plate H will be raised automatically whenever the front is swung off. The means consists of a bar or rod 1, which is pivotally connected with the plate C on the left side near the top, as indicated in Fig. 1, and at its other end with the rear side of the baffle plate near its middle. Thus the baffle plate will be raised and lowered automatically according to the movement of the plate C in opening or closing. It will be noted that the vertical side flanges f of the bars F prevent endwise movement of the bafiie plate H, and the front flanges f also prevent it being drawn forward in the act of rising or falling.

What I claim is 1. The combination, with the fireplace frame and a supplemental frame applied to the upper front portion of the same, of an anchoring device consisting of a bar secured at its front end to the supplemental frame and extended rearward therefrom substan+ tially as described.

2. The combination, with the fireplace frame and the supplemental frame applied to its upper portion on the outer side, of a bar secured to the supplemental frame and extending inward therefrom, said bar being provided on its rear side with a lateral lug adapted to engage the fireplace frameand thus hold the supplemental frame in place, substantially as described.

3. The combination, with a fireplace frame and a supplemental frame secured thereto and having inwardly extended bars and a baffle plate adapted to rest on such bars, substantially as described.

4:. The combination, with the fireplace frame and a supplemental frame applied thereto, of rearwardly extended bars secured to said supplemental frame, a baffle plate resting normally on these bars, a front plate hinged on the supplemental frame and means for loosely connecting it with the baffle plate whereby when the front plate is swung out laterally the'baffle plate is raised as shown and described. p

5. The combination, with a fireplace frame and a supplemental frame attached to the upper portion thereof, a front plate hinged on the supplemental frame and adapted to swing laterally, bars attached to the sides of the supplemental frame and extending inward therefrom, the same having side flanges f a baffle plate adapted to rest on said bars and to close within the said flanges and means for connecting the baffle plate with front the swinging plate, substantially as described.
